Transient Events from Neutron Star Mergers
Li-Xin Li, Bohdan Paczyński
Mergers of neutron stars (NS+NS) or neutron stars and stellar mass black holes (NS+BS) eject a small fraction of matter with a sub-relativistic velocity. Upon rapid decompression n…
Gamma-Ray Bursts as Hypernovae
Bohdan Paczyński
The energetics of optical and radio afterglows following BeppoSAX and BATSE gamma-ray bursts (GRBs) suggests that gamma-ray emission is not narrowly collimated, but a moderate beam…
Mass Determination With Gravitational Microlensing
Shude Mao, Bohdan Paczyński
We present a simple toy model of the distribution of objects responsible for gravitational microlensing. We use Monte Carlo simulations to demonstrate how difficult it is to determ…
Dark Matter -- Personal View
Bohdan Paczyński
Traditional evidence for large amount of dark matter is based on dynamical consideration for systems with . Recent observational and theoretical developments…
On the nature of gamma-ray burst time dilations
Ralph A. M. J. Wijers, Bohdan Paczyński
The recent discovery that faint gamma-ray bursts are stretched in time relative to bright ones has been interpreted as support for cosmological distances: faint bursts have their d…
